Mr. Granite is From Another Planet is the third book in the My Weird School Daze series.
Mr. Granite, a new third grade teacher, has so many strange ideas about how to make Ella Mentry Elementary School environmentally friendly that the students are sure he must be an alien.
- This is the first time that one of AJ's theories is actually true, even though most of his other theories aren't.
- It is revealed that some girls in AJ's class are afraid of the dark, as they got horribly frightened when the lights went off as AJ started pedaling slower.
